Why this rule existsrationale

Reusing a contact number across brands is the signature of one operator registering many businesses, which is the pattern brand-level accountability exists to prevent. Agencies trip it honestly by putting their own account manager on every client brand, and the collision is reported against the newest registration rather than against the practice.

How to fix itremediation

Name a representative who works for the business being registered and use their number. Your own staff belong on the CSP record, which is where a platform's contact details are supposed to live.

Check this yourselfattestation

No tool can settle this one for you. Here is the check, and what wrong looks like.

Is the representative on this brand an employee of the business being registered, with a number used on no other brand?

1Check who is named. An agency account manager on every client brand is the usual cause, and it is reported against the newest registration rather than against the practice.
2Your own staff belong on the CSP record, which is where a platform's contact details are meant to live.

What wrong looks like: One number spread across six client brands. The seventh registration is refused for a collision the earlier six caused.

Notesnotes

The collision is against every brand in the registry, which we cannot see. What the user has to do is use a different, genuine representative per brand — and if an agency has already spread one number across several brands, expect the next registration to be the one that is refused rather than the earlier ones.
