SIN application Canada 2026: documents and next steps

What a SIN is and who can apply

A SIN is a nine-digit number needed to work in Canada or access government programs and benefits. Service Canada administers the application. The number serves a different purpose from a provincial health card or a permanent resident card.

Anyone aged 12 or older can apply for their own SIN. A parent or guardian can apply for a minor. The source also describes registration for newborns through the provincial Newborn Registration Service.

There is no application fee. Do not confuse the free SIN application with costs that might relate to a different document or service. Use the Service Canada page for the official application route.

Service Canada no longer issues plastic SIN cards. You can view or print your SIN through My Service Canada Account. An expectation of receiving a new plastic card should therefore not be used as the measure of whether the process is complete.

An existing immigration or identity document is evidence for an application, rather than the SIN itself. Keep the document category and number distinct. This guide does not ask you to enter or send any of those numbers.

Choose online, in-person or mail application

The checked Service Canada guidance describes applying online as the faster route. It does not supply a verified number of days for online processing in this source record. Check the official page for current timing instead of relying on an estimate here.

An in-person application can result in a SIN during the visit if everything is in order. That condition matters: the guide does not promise completion at every visit regardless of documents or the applicant’s circumstances.

For mail applications, the supplied address is Service Canada, Social Insurance Registration Office, PO Box 7000, Bathurst NB E2A 4T1. Follow the official instructions for the documents required by that route.

Choose a route after checking what evidence it requires. Online submission uses digital copies of valid original documents. An in-person or mailed process should be prepared using the official instructions for that channel.

SettleCA does not act as an application intermediary. Follow Service Canada’s official page to submit. Finding a guide or preparing digital copies does not itself register a number or update an existing SIN record.

Primary status documents for a SIN application

Canadian citizens can use a provincial birth certificate or citizenship certificate as the primary document described in the supplied facts. The primary document establishes the applicable status category for the SIN process.

Permanent residents can use a PR card or Confirmation of Permanent Residence. The supplied record says COPR is acceptable within one year of becoming a permanent resident. Do not silently extend that acceptance period.

Temporary residents may use a work permit, a study permit with the required work wording, or a visitor record authorising work. A document’s title alone does not establish that every version is sufficient.

For a study permit, the checked facts specify wording such as may accept employment or may work. Review the actual document and official requirements rather than assuming every student document authorises work.

For a visitor record, work authorisation is part of the verified condition. A visitor record without that condition should not be described here as automatically sufficient. Use Service Canada’s instructions for your particular document.

Secondary identification and document language

Adults need a secondary identity document in addition to the primary document. The supplied examples include a passport, provincial or territorial identification, a driver’s licence or another Canadian government identity document.

The document must meet the official requirements rather than simply being something with a name on it. Check the accepted list for your situation. This guide gives the categories in the supplied facts without inventing a universal substitute.

Documents must be valid originals; online applications use digital copies of those originals. Keep the distinction between an original document and a digital copy prepared for an authorised online submission.

The source requires documents in English or French, or translated documents. Follow the official translation instructions where needed. This record does not verify translation costs or a processing estimate for translated evidence.

If names or details create a question not answered by the supplied facts, check Service Canada’s instructions. The guide does not invent an affidavit, name-change rule or additional fee to fill that gap.

Temporary SINs, expiry and maintained status

A temporary SIN begins with 9 and has an expiry date matching the immigration document. That expiry should be kept distinct from a permanent resident card expiry or the date of a health-card application.

The supplied facts say someone whose SIN has expired may keep working while waiting for a new immigration document if they have maintained status. The maintained-status condition is essential; expiry alone is not a general permission to keep working.

After receiving the new immigration document, update the SIN expiry with Service Canada. That is an update to an existing record. This guide does not treat a renewed immigration document as automatically updating every government service.

If you are unsure whether maintained status applies, use official immigration and Service Canada instructions for your situation. A general description in this guide does not determine an individual’s right to work.

Keep the immigration document and the SIN update as separate tasks in your own records. This helps identify whether a question belongs to the document issuer or to Service Canada’s SIN process.

Preparing for a visit and getting official help

Before applying, identify whether you are applying for yourself, a minor or a newborn, then choose the appropriate route. The verified age and document rules should be checked together instead of treated as independent shortcuts.

Prepare the primary status evidence and the secondary identity evidence required for adults. Check document validity and language before the application. A route that can be completed quickly still depends on the evidence being in order.

The supplied number for requesting forms is 1-866-274-6627. Use the official Service Canada page for its current instructions and contact options. This guide does not supply unverified opening hours or a call-back time.

For newborns, look at the provincial Newborn Registration Service route mentioned in the source. A parent’s own SIN record and a newborn’s registration are different records. Do not assume that a parent’s existing number covers a child.

Keep any application confirmation privately. If a question concerns a submitted file, the responsible service needs the appropriate record. SettleCA cannot look up a SIN, confirm a submission or replace missing official identification.

Keep the application, decision and document separate

An application is a request for the responsible agency to assess your situation. Preparing a form or finding this guide does not establish approval. Keep any official confirmation with the application record so you can distinguish what you submitted from what the agency decided.

Use the name of the service when organising documents. A health card, immigration document, tax credit and social insurance number serve different purposes. Evidence accepted for one process should not automatically be assumed to meet another process’s document rules.

For a personal question, start with the official page linked below and follow the route that fits your situation. A general guide cannot inspect a file or resolve a mismatch in your records. SettleCA does not collect identification, bank details or application documents.

Keep a note of which step you have completed and what remains outstanding. That can help distinguish a question about preparing an application from one about a submitted file. The appropriate next step may differ even when two people are applying for the same service.

Do not infer a service fee or processing time from an unrelated program. Where the supplied facts do not verify a figure, this guide directs you to the official source. A current official fee or status check is more useful than an unsupported estimate.

What this guide verifies and where to check next

The factual source record was checked on 11 November 2026. This guide was published and updated on 12 November 2026. Those dates describe the supplied evidence and editorial build, rather than a live check of your application or a guarantee that no official instructions have changed.

The official sources below are labelled by subject. Start with the source for this specific application, then use related sources only for a separate service you need. A cross-link does not mean the agencies share one application or that approval transfers automatically.

Before submitting, compare your documents and chosen route with the official instructions. If the instructions do not cover a detail of your situation, use the responsible service’s help route. This guide does not replace a personal eligibility decision.

The related guides can help organise other tasks, but they are separate processes. Complete the requirements for each service in its own context. A useful checklist keeps the program name, evidence and decision together without combining different eligibility tests.
