We searched for a congregation called "United Apostolic Church" in Ikirun, Osun State, and found no listing, page, map entry or directory record for it anywhere, and no mention of the contact name attached to any church in that town. The name "United Apostolic Church" does belong to real but unrelated bodies elsewhere, including a German-rooted federation in Europe and South Africa (Wikipedia), a US-based Apostolic Pentecostal group with a Facebook page (facebook.com/UACofJC) and a church page in India (facebook.com/upcindia.org), none of which show a Nigerian branch. Ikirun itself is a genuine town and an established church centre, with The Apostolic Church Nigeria running an Area headquarters there off Iragbiji Road, P.O. Box 42, Ikirun, Osun State (tacn-lawna.org) and the Apostolic Faith mission recording a congregation in the town since 1960 (apostolicfaithweca.org), but these are different organisations. The findings are summarized here for space; the full research was weighed in the review.
Our conclusion: No website or social page was given, and an independent search found no listing, map entry or directory record for a congregation by this name in Ikirun, nor any mention of the named contact person in connection with a church there. Ikirun is a real town with a strong Apostolic church presence, including The Apostolic Church Nigeria area headquarters and an Apostolic Faith congregation, so a small independent apostolic assembly there is entirely
We have asked this church for one piece of extra evidence: a photo, a link, its denomination, or a church that can vouch for it. The moment we can verify, this report is upgraded. Without a response, the listing is paused after 14 days.
