Is 434221 the same as the new postcode?
No. 434221 is a 6-digit area code. The new 11-character postcode (for example LA 01 A03 FK 01) identifies a single building, and there is no conversion table between the two. Find a building's new code on postcode.gov.ng. Old vs new postcode.

If a form asks for a "postal code" or "ZIP code" and doesn't mention NIPOST's digital postcode, enter the 6-digit code for your area. Use the new code only when the form asks for it. Which postcode to put on online forms.
