Cell / Landline Phone Call Scam Using 90# or 09#


If someone calls you on your landline or cellphone, instructing you to press 90# or 09#, please hang up immediately. There are scammers impersonating telecomunications technicans, who will call you, saying that they are conducting work on your telephone line. These people will ask you to press 90# or 09# to help them with the work that they are carrying out.

If you enter either 90# or 09#, this will allow these scammers to use your phone to make long distance calls.

Correction: sent in by an anonymous user:
This scam is possible only with certain types of vulnerable business phone systems that use PBX(private branch exchange) or PBAX(private automatic branch exchange) configurations. Such type of configurations are mostly used by businesses, hospitals, government and private organizations. In such configurations, pressing 9 is a standard signal to connect to an outside line through call forwarding, so when you dial #09 or #90, the scammer gains access to your line and can exploit your phone line in any unfair means. Such business phone systems are advised to disallow call transfers to these numbers and must be trained to handle such scammers. Mentioned in the reference section are definite guidelines from FCC to avoid such scams. Therefore, mobile phone users are NOT vulnerable to any such scams, but yes, one should always avoid call activity from strangers, as a safety measure
