The 3 booklets note that the first post office was located at Baptist Yard. It seems logical that the town’s first, more primitive post office would have been the location where the towns first telegraph messages were received, (the Victorian equivalent of email or texting.)
I can find no reason to believe that the photo is not the Baptist Yard.

Bedlington’s First Post Office and early Postal Presence in Bedlington
· The earliest record of a postal connection for Bedlington shows that in 1834 mail was already being handled for the town via the Morpeth post town. This means Bedlington had recognized mail services in the official British postal system from at least that year, even if there wasn’t yet an independent office building in the town itself
Historical timelines compiled by the Six Townships Community History Group, note that a post office with a telegraph system was present by in the Baptist Yard in1858. This suggests that a functioning postal office at least capable of handling mail and telegraph messages existed in the mid-1850s. As the postal system became more organised in the UK, Bedlington’s postal facility was officially incorporated into the national Post Office numbering system. This moved operations from a yard setting into a more formal postal classification.
By 1863, Bedlington had its own Railway Sub Office (RSO) designated with the code B75. An RSO was typically a postal facility associated with a railway station or rail mail sorting point, vital during the 19th-century expansion of mail transport via rail. After operating as a Railway Sub Office, the Bedlington postal facility later became an Independent Sub Office in 1905, indicating a more standard and autonomous local post office service. The postal office’s officially identity evolved over the 20th century, sometimes tied to railway-based names as the town and its services shifted:
Bedlington Colliery office existed and changed name in the early 20th century.
Bedlington Station became a recognised postal identity around 1936
Eventually the Postal Identity was simply “Bedlington”
