Meruoca had been a district of Vila de Acaraú since August 1861, located on the north bank of the Riacho do Salão, 260 kilometres west of the provincial capital Fortaleza. In January 1879, it became the Freguesia de Nossa Senhora da Conceição de Meruoca. This freguesia was subsequently transferred to Vila de Sobral. In November 1885, it was elevated to the status of Vila, but in October 1920, it was downgraded to Distrito in the Município de Massapê. This district was returned to the Município de Sobral in May 1931. Since November 1951, Meruoca has once again been an independent município.
As reported by the Rio press, there has been a post office there since January 1883.
The imperial postmark is the double circle MCE-0215a (Fig. Koester, in Carimbologia XXVII):

Im Januar 1879 wurde Meruoca zur Freguesia de Nossa Senhora da Conceição de Meruoca erhoben. Diese Freguesia ging anschließend zur Vila de Sobral über. Im November 1885 erfolgte die Erhebung zur Vila, die jedoch im Oktober 1920 zur Herabstufung zum Distrito im Município de Massapê führte. Dieser Distrikt ging im Mai 1931 zurück zum Município de Sobral. Seit November 1951 ist Meruoca wieder ein eigenständiger Município.
Wie die Presse aus Rio bekannt gab, gab es dort seit Januar 1883 ein Postamt.
