The USPS no such number status can be due to a variety of reasons.
In a perfect world, this means the addressee’s street number does not exist. To USPS, it’s merely an incorrect address.
However, there can be other causes.
Incorrect address info
Either the seller or the buyer entered incorrect address info. Ask the seller to confirm the house number on the shipping label with the address from your order information. Likewise, if you’re the seller, ask the buyer to confirm the address.
A new home or office
If it’s a new address, it may not be in USPS’s system yet. Contact your local jurisdiction for a new construction address.
What happens after this status?
Sometimes the package is returned to sender immediately (RTS). Here’s an example:

What you can do
Visit or call your local post office to check if the package is available for pickup. If you’re the seller, contact the customer asking them to contact their PO. Or take the time to contact the post office for them.
Tools to help with this Status
