Previous guest who relocated from another country has his post directed to my address

@ColetteP

What should I do? Do other AirBnB Hosts agree to guests using their home address as the guests address?

As @anon67190644 said, mark not at this address and/or return to sender and give it back to the post office.
I would never agree to a guest using my address as this can establish residency and they can apply for credit, ship something illegal, etc.
here’s a previous thread on this subject:

Watch for guests that use your address

I’ve had a previous guest use my home address to register in the UK for a car with the DVLA, driving licence ect to get enough ID to get a bank account. He’s here on a visa from China and clearly used my address as I’ve had a letter from the Dart crossing with a fine for non payment. I’ve had to phone the police, DVLA, dart crossing to make sure that we don’t end up with Bailliffs or the police on our door step. Or affect our credit rating. Any ideas how we can prevent this from happening again…
