We have a need to validate the area code on the phone number field from a list of acceptable area codes. Does anyone have a script to check the first three digits against a list of approved three digit combinations and validate?
The need is coming from a number of Google Smart Display campaigns that are generating fake leads from countries outside our target country for the client and in Google. The placement owers of these ads are trying to send additional quality signals into the platform to capture more budget from automated campaigns using machine learning signals against Google.
Any help is appreciated!
