Forgot to put house number on web purchase?

Question

I forgot to add the house number on my shipping form of a web purchase. Can I have it added on right now (Its been two days since I've ordered it and it takes 2-4 weeks to ship) or will the post office be able to find it?

Answer 1

It would be better if the house number was on there.

Answer 2

Try to reach the company by phone if they show a number.  If not, email them.

The post office will try to make the delivery and if you are extremely lucky they will deliver.  Most likely they will return it to the sender.
