How to cancel Unidata by mail
Collect the details you need
Unidata will look your account up from what the letter says, so check the account number, the phone number or service address being cancelled and the name on the account first.
Put the request in writing
Postbye writes the letter in Italian from our Italian template, because Unidata's address is in Italy. It opens with the subject line “Oggetto: Richiesta di cancellazione – [your name]” and asks Unidata to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Post it by certified mail to Unidata in Ponte Galeria, Italy, using the exact address below, and note the tracking number.
Keep the delivery receipt
The receipt dates your request. Look at your next statement for any Unidata charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Unidata cancellation letter goes
Unidata takes its post at Viale Alexandre Gustave Eiffel 100, 00148 Ponte Galeria, Italy, which is where a cancellation letter belongs.
The postcode 00148 belongs to Lazio, Italy, so this is where the envelope is delivered.
The letter greets the reader with “A chi di competenza,”; your own details sit under the labels Titolare dell'account, Indirizzo di fatturazione registrato and Email registrata.

Cancelling a phone or internet plan
Phone and internet providers tie cancellation to contracts, equipment balances and notice periods, so the request should name the exact line or service and ask for a final bill in writing.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
