Still i did’t received. I have my Original Passport with Immigration Status of Permanent Residence and Province Photo ID Documents. So please guide how i can get my SIN Number.
SIN Advisory Team
August 5, 2023 9:59 pmHi Avinash,
You need to submit a valid and original Primary identity document. You may find the list of acceptable documents on Canada.ca website. https://www.canada.ca/en/employment-social-development/services/sin/required-documents.html
Photocopies are not acceptable, it must be original. If you have missed any of the documents, you must replace it with the appropriate issuing agency or department.
Meanwhile, if you already have a SIN, you can just find it through T4, Notice of Assessment, etc.

August 30, 2023 5:50 pmHi
I applied for SIN on July 02, 2023 online and it has been almost 2 months but I have not received my SIN yet. Every time I follow up on my application over call or in person, I am asked to wait. Due to this issue I am facing financial difficulty also now as my employer cannot pay me without SIN. Please help what to do in this case?
SIN Advisory Team
September 1, 2023 3:39 pmHello Kawaljeet,
Generally speaking, you should not get any issue applying for SIN if your immigration document was able to validate against IRCC database during the SIN application process. Technically the employer can still pay your salary, just not able to issue your T4. You may visit your local Service Canada centre to find out if they can issue a letter for you to show proof to your employer that you are waiting for your SIN application.

September 8, 2023 10:00 pmI have applied for SIN number on August 2,2023 at Service Canada Centre and they didn’t issued me one by saying that a person with same name and date of birth as of mine still exist and they need to get it approved/checked by their higher authorities. I have asked whether our parents name is also same, so she said no parents name is different and issued acknowledgment letter to me, its been more than 20 business days still whenever i call to ask about my SIN status they only had one answer we are having high volume of applications ,we can’t give you any estimation how long it will take . I am having an virtual interview for amazon but they are not accepting acknowledgment slip and refusing to select me if i dont possess the SIN number till monday morning . What should i do ? I am suffering from unemployment because of their fault in processing application.
SIN Advisory Team
September 13, 2023 6:15 pmHello Jasmine,
First of all, do you already have a SIN? If so, you can just provide your SIN by showing documents such as old T4 or Notice of Assessment, etc.
If this is the first time you are applying and there is an urgency to receive your SIN, please bring your Primary Document(s) and Supporting Document(s) to your local MP’s office for assistance. They should be able to help you expedite your request.

September 29, 2023 2:42 pmhello,
I visited Service Canada on 11th September for my SIN, but I was told that they don’t have my information in the system and I was asked to fill out forms for my SIN application, all the information in my work permits is correct. I am left wondering what was the problem and why it is taking longer to process. Is there any office I can go to escalate the matter?
SIN Advisory Team
October 1, 2023 9:32 pmSometime it could be many different reasons. Most commonly is their SIN system is unable to match your information against IRCC’s system, that’s why they have to do a paper application. All Service Canada centres provides the same services, no centre is better then others.

November 23, 2023 4:06 pmi have applied for my SIN on september 2023 by in person and they send my application to the head office.Its been 2 months, i didnot receive my SIN. everytime i call them they are telling due to many applications they are receiving daily they are not able to process. Also they have all my required documents with them.i am new to canada and i am unemployed for about 2 months.What should i do now.
SIN Advisory Team
November 25, 2023 9:16 pmHello Anna,
As far as we know, not having a SIN should not prevent you from look for work because what employer should be looking for is your Canadian status (e.g. PR or Work Permit). If you are in a rush to obtain your SIN and have tried all the necessary way to communicate your urgency with Service Canada, you may want to visit your local MP’s office for assistance.

January 3, 2024 12:43 pmDear sir,
I applied for an online SIN few days ago. My email id got hacked. I need to change my email id in the application. How do I do that? I tried contacting the concerned authorities but didn’t get any response from them. Please help!!!!!
SIN Advisory Team
January 22, 2024 2:03 pmHello Shreeya,
In this case, I would suggest you to visit your local Service Canada centre to renewal or apply your your SIN with your official immigration documents. The SIN office may send you an email notification to tell you to log into your MSCA to view your Confirmation of SIN letter. No documents will be mailed as attachment from SIN office.

January 8, 2024 10:39 amMy study permit has expired and the social insurance number with it, two months before I applied to renew my study permit and I got a confirmation to my GCKEY that they accepted my request but the study permit will arrive after six weeks of the confirmation, my question is can I renew my sin with the confirmation letter that I received to my GCKEY? or I wait for my study permit.
SIN Advisory Team
January 22, 2024 2:00 pmHello Moussa,
You will have to wait for your new study permit in order to renew your SIN expiry. Getting the GCKEY is only a way to let you submit your information online, but it is not a confirmation of your SIN renewal. For more detail, you may contact SIN office directly.

Can I work without SIN Number?
SIN Advisory Team
January 29, 2024 1:31 pmYou may technically start working while waiting for your SIN. Remember, it is your Work Permit that allows you to work. SIN is needed for your employer to file your social security contribution. You may contact SIN call centre to follow up with the status.

May 10, 2025 7:24 amHello,
I have a 17 year old and a 16 year old secondary school students in Canada who wants to work for the summer and need SIN. How can I obtain it because the last time we visited the office, they were not given.
SIN Advisory Team
May 12, 2025 11:31 amHi Bola,
To obtain a Social Insurance Number (SIN) for your 16- and 17-year-old children so they can work in Canada over the summer, it’s important to ensure the correct procedure is followed, as they are legally eligible to apply for a SIN. In Canada, anyone aged 12 or older can apply for their own SIN, and individuals aged 16 and 17 do not need parental consent to apply. If your previous attempt at a Service Canada office was unsuccessful, it may have been due to missing documents, incorrect documentation, or because the children were not present themselves — since applicants over the age of 12 must apply in person or online themselves.
There are two main ways your children can apply for their SIN: online or in person. The online application is usually more convenient and efficient. To apply online, go to the official Service Canada SIN application website at https://www.canada.ca/en/employment-social-development/services/sin/apply.html. They will need to upload a primary identity document such as a Canadian birth certificate, permanent resident card, or a valid study or work permit. If they are international students, their study permit must state that they “may work” or “may accept employment” in Canada — otherwise, they will need to request an amendment through Immigration, Refugees and Citizenship Canada (IRCC) before applying for a SIN. Additionally, a proof of address is required for online applications — this could be a utility bill, bank statement, or government correspondence with their name and address.
Alternatively, you may apply in person at a Service Canada Centre, which can be helpful if there are any issues with online submission. However, it is crucial that your children attend in person with all original documents, as parents cannot apply on their behalf at this age. You can find the nearest Service Canada office and check hours of operation here: https://www.servicecanada.gc.ca/.
To avoid delays, ensure all documents are current, valid, and in the required format. If your children are temporary residents, double-check their immigration documents for work eligibility conditions. Following the correct application process and presenting the proper documents should allow them to successfully receive their SIN and begin working legally this summer.

July 2, 2025 1:06 pmHello they Misspell my name in my passport before i became a citizenship, then after i got my SIN card i corrected my name officially in Ontario Canada, by the way this was in 2001 . recently am applying for Canada Dental Program and notice the different between my sin card and my other papers (One letter only but still different) , now how to correct my name in my SIN Card , what do i have to do?
SIN Advisory Team
July 6, 2025 4:47 pmHello Nano,
The current rule with the name appearing on SIN file is based on the name of your Primary Documents. Depending of the situation, if you were born in Canada, the name on the SIN file will match the name on your provincial birth certificate. If you were a naturalized Canadian citizen, the name will match what is written your Canadian citizenship certificate. If there is a spelling error in your Primary Document, then you will have to perform a Name Change request with the provincial government service.
