I don't know how to send a postal code.

Postal code is the coded data of each postal point and its surrounding areas, and it is a convenient and fast delivery destination for postal delivery. Fill in the upper left corner and lower right corner of the envelope by the cover author, give it to the post office or mailbox, send it to the recipient by the post office, and return the postal code number of the original address.

If the cover author wants to know the zip code, or wants to tell the other party how to send it, there are many ways. Both parties can send it by phone, SMS, QQ, website and online.
