Members of the PCS Union working in Durham, Glasgow, Liverpool, London, Newport, Peterborough and Southport will strike from 3 April to 5 May.
Staff in the Passport Office in Northern Ireland are currently being balloted and may join the action subject to the ballot result.
The action is an escalation of the union’s long-running dispute with the government over working conditions and is likely to have a significant impact on the delivery of passports ahead of the summer season.
