Description: Port an existing phone number into Surge or host an external number to route its messaging traffic through Surge.
# Importing a Number
If you have an existing phone number with another provider, you have two options for bringing it into Surge: **porting** (transferring ownership) or **hosting** (keeping ownership with your current provider while routing traffic through Surge).
Both paths are currently handled through Surge support. API support for number imports is planned.
## Porting
Porting transfers your number from another carrier or provider into Surge's ownership. After porting, Surge owns and manages the number directly: you pay Surge for the number, and your previous provider's contract for that number ends.
**When to port:**
- You want to consolidate all messaging under a single provider
- Your previous provider relationship is ending
- You want full Surge management including TCR campaign registration
**What to prepare:**
- Your current provider account information
- Proof of ownership (typically the latest bill or account statement)
- The specific phone number(s) you want to port
**Expected timeline:** Number porting typically takes 2–4 weeks depending on your current provider's responsiveness.
## Hosting
Hosting lets you keep the number registered with its current provider while routing its messaging traffic through Surge. The number stays in your current provider's account; you configure it to forward inbound messages and calls to Surge.
**When to use hosting:**
- You want to try Surge without committing to a full port
- Your number has contractual requirements that prevent porting
- You're using the same number for purposes outside of SMS
## How to start
Contact Surge support at `support@surge.app` with:
- The phone number(s) you want to import
- Whether you want to port or host
- Your current provider name
Support will walk you through the specific requirements for your situation.
