Primary sources: GOV.UK — Prove your right to work to an employer (

gov.uk) and the Home Office Employer’s guide to right to work checks. Last verified 3 July 2026 —
share codes are free, generated from the UKVI account/eVisa,
valid 90 days, reusable within that period, checked by employers with the code plus date of birth; right-to-work share codes are 9 characters beginning with
W (format per established employment-law summaries of the Home Office scheme — the letter distinguishes them from right-to-rent codes). British and Irish citizens: passport or Irish passport card,
current or expired, for a manual check; certified IDSP/digital identity checks available only for
valid British/Irish passports (route live since 6 April 2022); alternative document combinations listed on GOV.UK. Employer duties: check
before employment starts; check
all applicants the same way (Home Office code of practice on avoiding unlawful discrimination; Equality Act 2010);
retain evidence for the employment plus 2 years; the check is free to the worker. Civil penalty context: up to
£60,000 per worker for repeat breaches (£45,000 first breach) since the February 2024 uplift — stated as employer context, not worker risk. eVisa transition: BRPs phased out with most cards expiring
31 December 2024, status unaffected and held digitally in the UKVI account; expired BRPs remain usable
to access/create the UKVI account under current transitional Home Office guidance (an easement with its own end date — check GOV.UK if reading much later); UKVI account recovery and the UKVI resolution centre stated qualitatively with contact routes deferred to GOV.UK (phone numbers deliberately not printed — they change). Employer Checking Service: free, used for in-time outstanding applications or status the online system cannot show; a
Positive Verification Notice gives the employer a 6-month statutory excuse, then a follow-up check. Confidence: High on the share-code mechanics, 90-day validity, free-to-worker, equal-checking duty, retention period and ECS/PVN 6 months (GOV.UK + Home Office employer guide); Medium on the W-prefix (consistent secondary sources, not stated on the public GOV.UK start page). Scope: UK-wide — immigration is reserved. Not legal or immigration advice; personal immigration advice is regulated (OISC / qualified lawyers).
