What Phone Number Should My Small Business Use?

The short answer

Pick one main phone number the business owns and controls, and use it everywhere: your Google Business Profile (GBP), website, listings, signs, trucks, and cards. Google says to use a local number instead of a central call center number when possible, and that the number must be under the business’s direct control. Add separate department numbers only when they make routing or tracking clearly better.

What this tells Google and AI

Your phone number is one of the core details Google, Bing, Apple, directories, and artificial intelligence (AI) tools use to match information about your business across the web. When the same number shows on your profile, website, and listings, they can be more confident it’s all one real business. A local number also fits Google’s guidelines. A number you lose control of, or one that changes often, breaks that match and sends callers to the wrong place.

What this means

This page covers two outline lines:

• 12.3.1 Main number: the one public number for the business.
• 12.3.2 Department numbers: extra numbers for sales, service, or billing, used only when they help.

The main number can be a landline, a mobile number, or a number from an internet phone service that rings on several phones. What matters is that the business owns the account and can move the number if it changes providers.

Made-up example: The owner of Tall Pines Tree Service has been using his personal cell. He gets a local business number from an internet phone service, set to ring his cell and the office. He puts that number on his GBP, website, truck wraps, and listings. His personal cell goes back to being personal, and if he hires an office manager, calls can ring her phone too without changing the number.

Why it matters

• Consistency builds trust. Matching details across listings helps search engines connect them (see 19.7 Entity Consistency).
• Google has rules about phone numbers. Its guidelines say to use a local number when possible, keep the number under the business’s direct control, and not use numbers that redirect callers to other businesses.
• Personal numbers trap you. If the business number is someone’s personal cell, it leaves when they do.
• Too many numbers confuse people and create mismatched listings.

Who this applies to

Every business that takes calls. Online-only businesses that don’t take calls can hide the number on their GBP, but should still have one for verification and account recovery.

How to do it

1. Choose a provider that lets the business own the account and lets you move (port) the number later.
2. Pick a local number with an area code your customers recognize. Toll-free numbers can be added as extras if they help.
3. Register the account to the business, with a business email and two people who can sign in.
4. Set up routing so calls ring the right phones and go to voicemail with a clear greeting (see 12.4 Voicemail and Call Routing).
5. Put the number everywhere, written the same way: GBP, website, Bing Places, Apple Business, directories, social profiles, email signatures, invoices, signs, and vehicles (see 14.1.4 Phone).
6. Decide on department numbers. Add one only if it routes calls better, such as a separate billing line, or helps you measure something you’ll act on (see 12.3.3 Call Tracking). Your GBP allows a primary number and up to two more.
7. Assign who answers and who returns missed calls (see 12.3.4 Call Ownership).
8. Record it in your Master Business Record and access inventory.

What proof to keep

• Phone provider account details and the business as account owner
• A list of every number, what it’s for, and where it’s published
• Screenshots of listings showing the main number

Common mistakes

• Using the owner’s personal cell as the public number.
• A number owned by a marketing agency. If you part ways, the number may go with them.
• Different numbers on different listings.
• Too many department numbers for a small team.
• Changing numbers without updating every listing. Old numbers linger for years in directories.

When to get help from a pro

Your phone service provider can help with porting, routing, and multiple phones. Questions to ask:

• Is the number registered to my business, and can I port it out if I leave?
• Can calls ring several phones at once, and go to voicemail after hours?
• What does it cost to add a second number?

[Bill: add a short note. For example, a client who lost their main number when they left an agency or changed carriers, and how it affected calls and listings.]

Questions people ask

Can I use my cell phone number for my business? You can, but it’s better to get a business number that can ring your cell. That way the business owns it and you can add people later.

Local or toll-free? Google says to use a local number instead of a central call center number when possible. A toll-free number can be an extra.

When do I need separate numbers? Only when they clearly help route calls or measure results you’ll act on.

How many numbers can I put on my Google Business Profile? A primary number plus up to two more.

Audit check

• Question: Does the business have one main local phone number, owned by the business, shown the same way on every listing?
• Pass looks like: Business-owned account, local number, same number on GBP, website, and listings, extra numbers only with a clear reason.
• Fail looks like: Personal cell, agency-owned number, mismatched numbers, or many numbers nobody can explain.
• Evidence to collect: Provider account screenshot, the number list, and listing screenshots.
