I am trying to update phone number in a branch location of Bank. But I can not do it. The number will be phone number. The personal number is inputted a few years ago. Now he is left his job. He is boring very much beacuse many people is calling for contact with branch via google map. Now need help to update phone number instead of the mobile number.
@Mahmudhun_Nabi estimado por lo menos en Argentina no está permitido pero no es por Google Maps es por una cuestión de seguridad hacia los usuarios del banco ya que es información sensible.
Por lo tanto solo las entidades bancarias son las únicas que puede cambiar dicha información.
There has been a hard restriction about the bank-related categories since a few years ago so in most cases it is not possible to change their data as @Maximilianozalazar mentioned. If the bank has a dashboard in Google Business Profile, then it is better to ask the bank to update the phone number through it.
As a user, the best practice is to request the issue in the Google Maps support forum. There, experts could escalate the issue to Googlers for a fix.
The bank should claim and centrally manage its business entries @Mahmudhun_Nabi as others have mentioned Local Guides are restricted from these changes to help prevent fraud and scams.
