What to include in a caller-ID authorisation request

Most caller-ID approvals are delayed by missing documents, not the review itself. A checklist for number ownership, brand, campaign details and consent evidence.

By Priya Natarajan, Compliance LeadUpdated 1 min read

Before we present a number as your caller ID, we need to know you have the right to use it. When a request stalls, it is almost always because one of the documents below is missing. Sending them together usually means a single review.

Proof you can use the number

  • A recent invoice or portal screenshot from the number provider showing the number and your company name.
  • If the number belongs to a client, a letter of authorisation from that client naming you and the numbers.
  • For numbers we supply, nothing extra: we already hold the record.

Brand and campaign details

We ask who the called party will think is calling and why. A short description is enough: the brand name, the purpose of the calls, the destination countries and expected daily volume. This lets us check the request against the caller-ID rules for each country, some of which require a number from the destination country or restrict mobile CLIs.

For IVR and press-1 campaigns we also need to see how consent was collected: the form or script, a sample record with a timestamp, and how people opt out. Rules on automated and prerecorded calls are strict in many countries, and we review these campaigns before they go live.

Checklist

  1. Number list

    Every CLI you plan to present, in E.164 format. The E.164 formatter converts local formats in bulk.

  2. Ownership

    An invoice, provider record or letter of authorisation for each range.

  3. Campaign

    Brand, purpose, destination countries and expected daily volume.

  4. Consent

    For automated or prerecorded calls: how consent was collected and how people opt out.
