Give clients a business number for calls & texts.

When you work for yourself, your mobile number ends up on proposals, invoices, and client contact lists. Numberline gives your business its own local or toll-free number on the phone you already carry.

Learn how a second phone number works on one phone, and how to call clients back from the business number.

Questions freelancers & consultants ask

Does my personal number stay private?
Yes. Clients see the business number when they call you and when you call back from the Numberline app.
Can I use it by myself?
Yes. Numberline works for one person: calls ring your mobile during the hours you set. Users are unlimited, so you can add people later at no cost.
Do I need a second phone or a SIM card?
No. Calls ring the mobile you already carry. The Numberline app places business calls over the internet.
Can clients text my business number?
Yes. Texts land in your Numberline inbox, where you reply as the business. Carriers require registration before the number can send. We file it for you, and sending starts after carrier approval. Texting is included.
What happens when a client calls after hours?
Set business hours on the number. After hours, callers hear a closed-hours greeting and leave a business voicemail. It is emailed to you with the recording, a transcript, and an AI summary.
What number shows when I call a client back?
Calls you start in Numberline show the business number. Calls from your phone’s own dialer show your personal number. See how to make business calls from an iPhone.
