Leaving employee: keep the number with us or hand it over?
The number is on business cards and in customer signatures, so it has business impact. Legally: a number registered to the company is the company's, a number on the employee is theirs. Practically: always register business numbers in the company name, avoids this discussion entirely.
Try this first
- 1Check with the carrier whose name the number is in (company or employee).
- 2Company number: new employee inherits it, or forwards to a successor with announcement.
- 3Personal number: employee may port to new employer or personal plan (MNP via new carrier).
- 4Prevent next time: register all new business lines in the company name and have a KvK extract as proof.
When to bring us in
