Overview
US carriers only reliably deliver business texts, and show business calls as trustworthy, when the number is tied to a registered business. Custral registers your numbers under your own business, not under Custral’s. You enter your business details once, in Settings → Phone & SMS → Registration, and every registration below uses them.
Everything is checked by Twilio and the carriers, so it takes from a few hours to
a few days. The Registration tab shows where each one stands, and you can leave
the page while it runs.
Using it
1
Enter your business
Go to Settings → Phone & SMS → Registration. Enter your business details (legal name, EIN, address, website, an
authorized representative) and your texting details (what you send, sample messages, how people opt in,
and your privacy policy and terms links).
2
Submit
Submitting charges a one-time registration fee (in credits) and sends your business for review. If anything is
missing or not accepted, the tab says which field before anything goes to carriers.
3
Add calling details
Once your business is approved, verified calls start on their own. Set a caller name (up to 15 letters,
numbers, periods, commas and spaces) and, for spam protection, tell us what your calls are for and about how
many you make a day.
4
Toll-free numbers
If you have a toll-free number, open Details next to Toll-free numbers and add how people opt in, a link
showing the opt-in, and how many texts you send a month.
Brand types for local texting
- Sole Proprietor: no EIN required. Lower daily throughput. Caller name and spam protection need an EIN, so they aren’t available.
- Standard: requires an EIN. Higher throughput, full vetting.
- Low-Volume Standard: a lighter Standard tier.
Costs
Local texting registration uses a one-time amount of Custral credits (covering Twilio’s brand and campaign fees). If your balance is too low, top up and resubmit.Opt-out is automatic
Carrier rules require honoring opt-outs. Anyone who replies STOP is automatically opted out and Custral will refuse further texts to them; they can reply START to opt back in.Troubleshooting
When reporting an issue, include the request id shown in the error toast. It links the in-app error to the server
logs.
