  1. Please help me with that of Cameroon Road by East

    Chisom asked on · 2 people asked this

    Cameroon Street in Umuahia Urban 1, Umuahia North LGA, Abia State has the old 6-digit postcode 440234. Our listing is for Cameroon St. only; we don't list a separate code for Cameroon Road by East, so we can't confirm that one. You can see the full area on our Umuahia Urban 1 postcodes page. Old codes cover a postal area, not a single building. For a building-level code, use postcode.gov.ng/find.

    We don't list a separate code for Umuode Road yet. The only Umuode entry we have is Umuode Street in Asaokpuja, Aba, which uses legacy code 450261. That code covers a postal area, not a single building, so check the Aba page for the full area list. For the new building-level postcode, use NIPOST's postcode finder.
