Regulatory Update: 📢 Important Update: UK Sender ID Whitelisting Requirement

Scheduled for Jan 19, 12:15 PST - Jun 18, 13:15 PDT

Scheduled

To comply with UK regulatory requirements, it is mandatory to whitelist Sender IDs for all traffic towards the United Kingdom.

Any traffic sent using non-whitelisted Sender IDs will be blocked.

Please note that the exact enforcement date has not yet been confirmed. However, we strongly recommend ensuring compliance as soon as possible.

All Sender IDs currently used by Telesign clients have already been whitelisted.

Action Required

If you plan to introduce new Sender IDs, please submit your requests in advance to avoid any potential service disruption once blocking is enforced.

Required Details for Sender ID Whitelisting

To whitelist a new Sender ID, please provide the following information:

Sender ID
Company Name
Company URL
Important Reminder

The reselling traffic is not permitted in the UK.

Thank you for your attention to this important update. If you have any questions or require assistance, please reach out to us.
