This article covers how to tie phone contacts to a function instead of an individual, contact lists by purpose and department, parcel receiving rules, and checklists.

Intro: Don't Put a Personal Number Under "Not Sure? Call Here"

At the visitor entrance of a factory or office, you often see a sign like this:

If you're not sure, please call this number.

And the number belongs to one particular employee.

At first glance it looks helpful.
Visitors and couriers have someone to call when they're lost.
If someone picks up, they can be guided.
Fewer people get stuck at the door.

But this is a pretty dangerous design.

Because the person whose number is on that sign becomes the company's bin for unsorted inquiries.

A courier shows up.
A parcel arrives for another department.
A visitor doesn't know who they're meeting.
A contractor doesn't know who to ask for.
A salesperson can't find the person they have an appointment with.

Every single time, the phone rings for the one person named on the sign.

That's not because they're the receptionist.
It's not because they're the official main contact either.
It's simply because nobody designed the company's entrance flow.

In this article I'll call this structure the "Call-Me Box."


1. The Feeling Everyone Has: Why Am I Receiving Another Department's Parcels?

First, here's where the frustration comes from.

A parcel arrives for another department.
A courier is standing there.
They don't know the department or the person it's for.
They look at the sign at the entrance.
Your phone number is on it.
Your phone rings.

And now it's your problem.

  • Ask who the parcel is addressed to
  • Hunt for the right department
  • Contact someone in that department
  • Look for somebody else if they're out
  • Decide whether to accept the parcel
  • Sometimes end up holding the parcel yourself
  • Then follow up with the person it was meant for

And you think:

Why do I have to take another department's parcel and chase people about it?

That's a perfectly natural reaction.

A parcel should be received by the department it's addressed to.
If they're out, a stand-in within that department should receive it.
If the destination is unknown, an official first point of contact, such as general affairs, the security desk or the main reception, should sort it out.

One individual does not have to become the whole company's lost-at-the-door center.


2. The Real Problem: The Phone Contact Is Tied to a Person, Not a Function

The most important rule of designing phone contacts is this:

Tie the contact to a function, not to a person.

A bad design looks like this:

If you're not sure, contact [Name].

That's the same as making that person the company's main reception.

A good design looks like this:

Hiring matters: HR main line.
Deliveries and couriers: the receiving department or the general affairs main line.
Construction and inspections: facility management.
Sales meetings: the department you have the appointment with.
Destination unknown: main reception or the security desk.

You split contacts by purpose like this.

Visitors and couriers don't know the company's org chart.
They may not know exactly which names or departments exist.
That's exactly why the entrance guidance has to be easy to follow.

But the fallback must not be a person.

If it is, everything flows to that person.


3. The Modern Term for It: Unsorted-Inquiry-Box Laundering

If you wanted to put this in trendy terms, it's unsorted-inquiry-box laundering.

The company is pushing inquiries it hasn't managed to sort onto one specific person.

  • Nobody knows which department a parcel belongs to
  • Nobody knows who a visitor is here to see
  • Nobody knows where to call
  • People are lost at the entrance
  • The main reception isn't doing its job
  • There are no contact points organized by purpose

All of this gets soaked up by:

If you're not sure, contact [Name].

That isn't design.
It's dumping work on an individual.

Another name for it is turning someone into a lost-at-the-door center.

There's a hole in the company's entrance.
And someone has stuck the phone number of a person who can handle things over that hole.
Every inquiry from outside drops straight into it.

That's genuinely risky.


4. Why the Number at the Very Top Gets All the Calls

The couriers and visitors aren't at fault.

There's a sign at the entrance.
There's a number at the top.
It says "if you're not sure, contact this number."

So they call it.

That's only natural.

That's why a personal number at the top gets flooded with calls.

Couriers don't know the company's internal situation.
They can't tell that "this person isn't the first point of contact."
They can't tell that "this person works in HR and doesn't handle other departments' parcels."
They can't tell that "this person is often in meetings."

They're just calling what the sign tells them to call.

So the problem isn't the users. It's how the sign is designed.

The sign turns an individual into the first point of contact.
That's why the calls go to the individual.

It really is that simple.


5. How Parcel Receiving Should Work

A parcel for another department should flow like this:

Courier
↓
Confirm the destination department or person
↓
Contact the destination department's main line or the person in charge
↓
The responsible department receives it
↓
If they're out, a stand-in within the department receives it
↓
Only if the destination is unknown, the main reception, security desk or general affairs main line does the first check

With this flow, responsibility is clear.

If the destination department is known, that department receives the parcel.
If the person in charge is out, the department decides on a stand-in.
If the destination is unknown, the main reception checks.

There's no need to pull in some unrelated individual.

The bad flow looks like this:

Courier
↓
If you're not sure, contact [Name]
↓
[Name] takes the call
↓
[Name] looks for the destination department
↓
[Name] contacts the person in charge
↓
[Name] sometimes receives the parcel
↓
[Name] later tells the person in charge

This is textbook parcel-receiving laundering.


6. What the Entrance Sign Should Look Like: By Purpose and Department

The visitor entrance sign should be organized by purpose and by department.

Example of an entrance sign

Purpose Who to contact
Deliveries, couriers, handing over parcels Destination department or general affairs main line
Interviews, hiring matters HR main line
Construction and inspection contractors Facility management or the department that requested the work
Sales, business meetings Department you have the appointment with
Emergencies, accidents, illness, suspicious persons Security desk, general affairs, main line
Destination department or person unknown Main reception, security desk, main line

With this, visitors can call the contact closest to their purpose.

The key point here is not to make a person the fallback when things are unclear.

When it's unclear:
the main reception.
The security desk.
The general affairs main line.
The company main number.
A duty desk.

Handle it by role, not by a personal name.


7. Decide the Primary, the Secondary and the Out-of-Office Contact for Each Department

If you're making a list by department, decide not only the primary contact but also who covers when they're away.

Example of a department contact list

Department Primary contact When away Final check
Engineering Engineering main line / person on duty Engineering team lead Department manager
Sales Sales main line / sales assistant Sales team lead Sales manager
Quality assurance QA main line / person on duty QA team lead QA manager
HR HR main line Stand-in within HR HR manager
General affairs General affairs main line Security desk / facility management General affairs manager
Facilities and construction Facility management Requesting department General affairs manager

Just lining up people's mobile numbers and extensions haphazardly isn't enough.

Who is the primary contact?
Who is it when they're away?
Which department is ultimately responsible?

You have to decide all of this.


8. How to Properly Write "If You're Not Sure, Contact…"

"If you're not sure, contact…" isn't bad in itself.

The problem is when what follows is a personal number.

The right way to write it is:

If you don't know the department or person you need, please contact the main reception.
We'll confirm your purpose and connect you to the right department.

Or:

For parcels or visitors with an unknown destination, please contact the security desk or the general affairs main line.

Make it a functional contact like this.

The wrong way to write it is:

If you're not sure, contact [Name].

That just dumps unsorted inquiries on an individual.


9. Conditions for Putting a Personal Number on the Sign

If you absolutely must put a personal number up, you have to state its scope.

For example, for an HR person's number:

For HR-related visitors, interviews and hiring matters only, please contact the number below.
For parcels, deliveries, construction work or sales visitors for other departments, please contact the destination department or the general affairs main line.

With this, the scope is clear.

The conditions for putting up a personal number are:

  • The purposes it covers are clear
  • The purposes it doesn't cover are clear
  • There's a stand-in for when they're away
  • It's clear they aren't the first point of contact
  • Things don't get stuck when they're in a meeting or out
  • It's formally defined as part of their job
  • If needed, there's an allowance, authority and a process behind it

If you can't meet these, don't put a personal number up.


10. What You Can Do to Protect Yourself

What if your number is already up there as the "if you're not sure" contact?

1. Don't pick up during meetings or focus time

If you're not the official first point of contact, you don't have to be reachable all the time.

Set yourself as in a meeting.
Don't call back.
Have them contact the right department directly.

This isn't slacking off.
It's a defense so you don't plug a hole left by a design mistake with your own phone.

2. If you do pick up, hand it back to the right department

Even if you've already taken the call, don't take it on yourself.

Please contact the destination department directly.
I'm not the first point of contact, so please check the department contact list.
If you don't know the destination, please contact the general affairs main line.

That's all you need to say.

3. Don't accept parcels

Basically, don't accept other departments' parcels.

Once you accept one, it easily becomes:

Just ask this person.

If you do accept one, keep a record of it as an exception.

Normally the destination department receives this, but I handled it temporarily because it was urgent. From now on, please have the destination department receive it.

4. Ask the company to change the sign

Tell the company plainly.

On the visitor entrance sign, my number is listed as "if you're not sure, contact here," so parcels, couriers and visitors for other departments are all concentrating on me. I'm not the company's first point of contact, and I can't always answer because of meetings and so on, so I'd like to change it so that main contacts by purpose and department are at the top, and unknown destinations are routed to general affairs, the security desk or the company main line. For parcels and visitors other than HR matters, please have the destination department or a stand-in within that department handle them.

That's enough.


11. Sample Request Text for an Internal Proposal

Here's wording you can use as is.

About the contact information on the visitor entrance sign: my number is currently listed as "if you're not sure, contact here," so the first contact for other departments' parcels, couriers and visitors is concentrated on me.

I'm not the company's first point of contact, and I can't always answer because of meetings and so on, so I'd like to change this by showing main contacts by purpose and department at the top, and routing unknown destinations to general affairs, the security desk or the company main line.

For parcels, I'd also like the destination department or a stand-in within that department to receive them as a rule.

I'll handle things within my own area, such as HR-related visitors and hiring matters, but for other departments' parcels, deliveries, construction work and sales visitors, please review the sign so that people contact each responsible department directly.

13. Common Bad Sign Wording

Bad wording makes one person absorb all the unsorted inquiries.

Bad example 1

If you're not sure, please call [Name].

This turns a person into the reception.

Bad example 2

Visitors, please come this way.
[Name], ext. XXXX

This is too vague about the purpose.
It doesn't say what kind of visitor it's for.

Bad example 3

Deliveries, visitors, other: [Name]

This makes one person absorb "other."
"Other" is the most dangerous category.

Bad example 4

If you don't know who to contact, please ask a nearby employee.

This design tosses unsorted inquiries to whoever happens to be on the floor.


14. Examples of Good Sign Wording

Good example

[Deliveries and couriers]
Please contact the destination department or person.
If the destination is unknown, please contact the general affairs main line.

[Interviews and hiring]
Please contact the HR main line.

[Construction and inspection contractors]
Please contact the requesting department or facility management.

[Sales and business meetings]
Please contact the department you have the appointment with.

[Emergencies]
Please contact the security desk or the general affairs main line.

With this, people can decide for themselves based on their purpose.


15. In One Line: Don't Use a Personal Phone as the Company's Main Reception

If I had to sum up this problem in a single sentence, it would be this:

Don't use a personal phone as the company's main reception.

And one more:

"Not sure? Call me" is not design. It's dumping.

The company entrance is where it meets the outside world.

If you put a personal number there that soaks up unsorted inquiries, visitors and couriers get lost.
That person gets burdened.
The responsible department's accountability gets blurry.
The history of who received which parcel gets blurry.
The phone rings even in the middle of a meeting.
Their real work gets interrupted.

That's why reception should be tied to a function, not a person.


Summary: Don't Plug the Holes in Your Entrance Flow With One Person's Phone Number

Writing a personal number under "if you're not sure, contact here" looks convenient at first glance.

But it may just be plugging a hole in the company's entrance flow with that person's phone.

Other departments' parcels.
Couriers.
Visitors.
Contractors.
Salespeople.
Inquiries with an unknown destination.

All of these end up flowing to one particular person.

That person isn't the receptionist.
Isn't the security guard.
Isn't the general affairs main contact.
Isn't a parcel receiving center.

So here's what the right design looks like:

  • Tie the phone contact to a function, not a person
  • Organize the entrance sign by purpose and department
  • When unclear, route to the main reception, security desk or general affairs main line
  • The destination department receives the parcel
  • When they're away, a stand-in within the department receives it
  • If you put up a personal number, limit it to specific purposes
  • Don't let unsorted inquiries drain into an individual

One last thing.

Don't run the lost-at-the-door center on one person's phone number.
"Not sure? Call me" is not design. It's laundering.
