Two Black Country register offices have removed the word marriage from their suites after the introduction of "gay weddings" and other new ceremonies.
The changes are taking place at both Wolverhampton - where signs now simply read "ceremony room" - and Stourbridge where they are reviewing their titles.
Wolverhampton's superintendant registrar said they wanted to reflect the diversity of their services.
Authorities across the country are said to also be considering the changes.
Teresa Reilly from Dudley Metropolitan Borough Council, which owns the Stourbridge Crown Marriage Suite, said: "In addition to marriages, the suites also host civil partnerships, renewal of marriage vows, baby naming, citizenship and commitment ceremonies.
"The signs have been removed while we consider whether they are appropriate or if any changes should be made."
She said local authorities had received guidance and advice from national bodies including the regulatory body LACORS (the Local Authorities Coordinators of Regulatory Services) about the possible "re-naming of services".
Holly Holdsworth from Wolverhampton Register Office said signs for "births, deaths and marriages" outside the office had not been changed.
