Best practices when using a TFN for A2P
Guidelines for using toll-free numbers for A2P
A toll-free number is a 10-digit number that begins with one of the following area codes: 800, 888, 877, 866, 855, 844, or 833. You can use toll-free numbers to send transactional messages only.
To purchase toll-free numbers, contact your Account Manager at Kantask.
When using a toll-free number as an origination number, follow these guidelines:
Don’t use shortened URLs created from third-party URL shorteners, as these messages are more likely to be filtered as spam.
Be aware that keyword opt-out (STOP) and opt-in (UNSTOP) responses are set at the carrier level. You can’t modify these keywords or other any other keywords, or the messages that are sent when users reply with STOP and UNSTOP.
Don’t send the same or similar message contents using multiple toll-free numbers. Carriers call this practice snowshoeing or number pooling and target these messages for filtering.
Because toll-free numbers are subject to content filtering, be sure your messages don’t contain any of the following types of restricted content:
|High-risk financial services||Payday loans|
Short-term high-interest loans
|Debt forgiveness||Debt consolidation|
Credit repair programs
|Get-rich-quick schemes||Work-from-home programs|
Pyramid or multi-level marketing schemes
|Phishing||Attempts to get users to reveal personal information or website login information.|
