Provisioning a Vanity
Provisioning a vanity short code can be a bit of a process, but it's worth it for the branding and recognition it provides. The approval process can take several weeks, so plan ahead.
You'll start by filling out a service approval form, which will be sent to each cellular network that delivers your messages. This form contains the details about your campaign and ensures you comply with each network's regulations.

The cell providers will review your application, and it's common to be rejected the first time, but you'll typically be approved quickly after revisions. Make sure to check what words your short code might spell, as this could be a reason for rejection.
For example, the number 37847 can spell both "FRUIT" and "DRUGS", so choose wisely. The provisioning and testing process can last up to 6 weeks, but it's essential for ensuring your campaign meets the networks' regulations.
Here's a step-by-step overview of the provisioning process:
- Filling out a service approval form
- Review and approval by cell providers (can take several weeks)
- Provisioning and testing (can last up to 6 weeks)
- Final approval and launch of campaign
