Getting a number

Search, buy, and configure your first number.

/tools/business-phoneNumbersBuy a number.

  • Country — US/CA/UK/AU/EU + many more.
  • Type — Local (geographic area code), Toll-free (800/888/877/etc.), Mobile (where available — UK, AU).
  • Filter — area code, vanity pattern ("contains 8888"), capability (voice, SMS, MMS, fax).

Available numbers stream in. Each shows capabilities and the monthly rental.

Buy

Click a number → Buy. Confirms the monthly rental added to your billing. Number is live within a minute.

Configure capabilities

Once owned, click the number to configure:

  • Voice routing — pick a call flow or set to ring a softphone.
  • SMS routing — store inbound messages, forward to email, or trigger a webhook.
  • Recording — record all calls automatically (legal compliance is on you — see consent requirements per jurisdiction).
  • Caller ID name (CNAM) — what shows on caller ID. US carriers surface this differently; we register the name you set.
  • E911 address — required for US numbers. Pop up triggers on first config. Without it, emergency calls don't work.

Porting an existing number

Bringing your existing number from another carrier:

  1. Numbers → Port number
  2. Fill the porting form (current carrier, account number, PIN if required, billing address on file there).
  3. Sign the LOA (letter of authorization). Suzko provides a template.
  4. Submit. Port takes 5–10 business days on average.

During the port, calls keep going to the old carrier until cutover day. Plan accordingly.

A2P 10DLC registration (US SMS)

For SMS in the US, carriers require A2P 10DLC registration if you're sending any application-to-person traffic (anything that isn't 1:1 conversation). Suzko walks you through it at /tools/business-phoneCompliance.

Without 10DLC, US SMS deliverability degrades over time. We push you to register early.
