What to do if…
you receive a seizure or detention notice for a parcel and you are told to contact an authority

Short answer

Pause and verify the notice is real before you contact anyone or share details. If it’s genuine, keep everything, identify any deadline on the notice, and respond in writing to the official address (not via links or unknown phone numbers).

Do not do these things

  • Do not call a number or click a link from an unexpected text/email “detained parcel” message (many are scams).
  • Do not pay “release fees”, “fines”, or “verification charges” via bank transfer, crypto, gift cards, or payment links.
  • Do not provide ID, bank details, or a signature “to release the parcel” until you’ve verified the sender independently.
  • Do not rush into a phone “interview” or written admission if the notice suggests criminal issues—get legal advice first.
  • Do not throw away the packaging, letter, or any tracking details (these can matter later).

What to do now

  1. Stop and check what you actually received (paper letter vs text/email).
    Genuine seizure/detention action is commonly communicated by a paper notice with a reference number, date, what was seized, who seized it, and what you can do next. Treat texts/emails demanding urgent action or payment as unverified until proven otherwise.
  2. Verify the sender independently (don’t trust a link or callback number).
    Use GOV.UK seizure guidance to confirm the process and the kind of paperwork you should have. If you need to contact an authority, use contact routes you found yourself on GOV.UK (or a main switchboard), and only use the address on the letter if it matches what you see on official guidance.
  3. If it’s a suspicious “missed parcel/detained parcel” text, report it and stop.
    Forward the text to 7726 (spam reporting), then delete it. Track any real delivery only via the courier’s official site/app that you access independently (not via the message).
  4. Photograph/scan everything and start a simple log.
    Keep: the notice, envelope (postmark), tracking number, order confirmation, item description, seller details, payment record, and any messages. Write down: when you received it, and any deadlines stated.
  5. Work out what the notice is asking you to do, and calendar the deadline today.
    UK seizure paperwork commonly separates:
    • Challenging whether the seizure was lawful (often by sending a notice of claim), and/or
    • Asking for the goods back (a restoration request).
      If you are challenging the legality of the seizure, there can be a strict time limit (often one calendar month from the date shown on the seizure notice). Use the date on your notice and do not assume you can file late.
  6. Respond in writing and keep proof.
    If you choose to respond, do it in writing, keep a copy of everything you send, and use a tracked method so you can prove it was delivered. If you’re making a restoration request, use an official template/format where available and stick to the facts.
  7. If there’s any suggestion of illegality, protect yourself before you talk.
    If the notice mentions prohibited items, controlled drugs, weapons, an interview, or an investigation, don’t try to “clear it up” in a rushed call. Consider getting prompt advice from a solicitor before replying or speaking to anyone, especially if you’re unsure what the parcel contains or who sent it.
  8. If you paid or shared bank details, act immediately.
    Contact your bank using the number on your card/app and say you suspect fraud. Save screenshots, call logs, and the exact wording of messages for later.

What can wait

  • You do not need to decide right now whether to “fight it” versus “let it go”—first verify authenticity and note deadlines.
  • You do not need to explain everything in one message—start by confirming the basics and asking what documents they require (in writing).
  • You do not need to confront the seller/sender immediately—save messages first.

Important reassurance

These notices are designed to feel intimidating, and scammers copy that tone. Taking a short pause to verify the source, preserve documents, and avoid rushed calls or payments is a sensible, protective response.

Scope note

This is first-steps guidance only: verification, avoiding common mistakes, and making a safe initial response. Anything involving potential criminal allegations or high-value goods may need tailored legal advice.

Important note

This is general information, not legal advice. Processes and time limits can vary depending on what was seized, who seized it, and what the notice says. If the notice mentions offences, interviews, or prosecution, getting advice from a qualified UK solicitor before responding can help you avoid accidental self-incrimination.
