What Is a Drug Identification Number (DIN)? A Guide for Americans Ordering from Canada
Published by the Canadian Medication Knowledge Centre at DrugsByCanada
Every year, thousands of Americans order prescription medications from licensed Canadian pharmacies to help reduce their medication costs. If you’ve researched buying medications from Canada, you’ve likely come across the term Drug Identification Number (DIN).
A Drug Identification Number is one of the easiest ways to identify medications that have been approved for sale in Canada. While it isn’t the only thing you should look for, understanding what a DIN is and where to find it can help you make more informed decisions when ordering medications from Canada.
In this guide, we’ll explain what a DIN is, why it matters, and what else you should watch for before placing an order.
What Is a Drug Identification Number (DIN)?
A Drug Identification Number (DIN) is a unique eight-digit number assigned by Health Canada to every approved drug sold in Canada.
Think of it as a medication’s official Canadian identification number.
Before a prescription medication can be legally marketed in Canada, Health Canada carefully reviews scientific data submitted by the manufacturer. This review ensures the medication meets Canadian standards for safety, effectiveness, manufacturing quality, product stability, recommended dosage, and product labelling.
Once Health Canada determines the medication meets these standards, it assigns the product its own unique Drug Identification Number.
Every approved prescription medication sold in Canada has a DIN.
Why Does a DIN Matter?
A DIN tells healthcare professionals and patients that the medication has successfully completed Health Canada’s regulatory review process.
For pharmacists, the DIN helps verify the exact medication, manufacturer, and strength before dispensing. It is also used for insurance processing, medication records, inventory management, and product recalls.
For patients, the DIN provides additional confidence that the medication has been reviewed and approved for sale in Canada.
Does Every Medication Have Its Own Unique DIN?
Yes.
Every unique drug product receives its own Drug Identification Number.
Even medications containing the same active ingredient often have different DINs because they may be manufactured by different companies, supplied in different strengths, or available in different dosage forms such as tablets, capsules, injections, or creams.
For example, a 5 mg tablet and a 10 mg tablet of the same medication each receive their own DIN. Likewise, two manufacturers producing the same generic medication will each receive separate DINs.
Where Can You Find the DIN?
The Drug Identification Number is usually printed directly on the manufacturer’s packaging.
Depending on the medication, you’ll typically find it on the outer carton, the bottle label, the blister package, or the manufacturer’s product label.
It is normally identified simply as DIN: XXXXXXXX.
If you are ordering medications from Canada, you will often see the DIN on the product packaging once your medication arrives. Canadian pharmacies also include it on the dispensing label.
DIN vs. U.S. National Drug Code (NDC)
Although both Canada and the United States use medication identification numbers, they are different systems.
In Canada, approved medications receive a Drug Identification Number (DIN) from Health Canada.
In the United States, medications are identified using a National Drug Code (NDC).
A Canadian DIN always contains eight digits, while an American NDC typically contains ten or eleven digits.
What Should Americans Watch for When Ordering Medications from Canada?
A Drug Identification Number is one important sign that you’re receiving a medication approved for sale in Canada, but it shouldn’t be the only thing you look for.
Make Sure the Medication Has a DIN
Legitimate prescription medications approved by Health Canada generally display a Drug Identification Number on the manufacturer’s packaging or product information. The DIN confirms that Health Canada has reviewed and approved that specific medication for sale in Canada.
Make Sure the Pharmacy Requires a Valid Prescription
A legitimate Canadian pharmacy will always require a valid prescription before dispensing prescription-only medications. If a website is willing to sell prescription medications without asking for a prescription, this should be considered a significant warning sign.
Verify the Pharmacy Has a Physical Canadian Presence
Reputable Canadian pharmacies are transparent about who they are and should be willing to answer questions about their licensing and dispensing practices.
Look for clear contact information, including a Canadian telephone number, email address, and an easy way to speak with a licensed pharmacist if you have questions.
At DrugsByCanada.com, if you’d like to verify where your medication will be dispensed or learn more about our Canadian pharmacy partners, simply complete our contact form, email us at info@drugsbycanada.com, or call us.

Because different medications may be dispensed by different licensed Canadian pharmacy partners, we’re always happy to provide additional information about the dispensing pharmacy upon request.
Expect Professional Packaging and Labelling
When appropriate, medications should arrive in properly labelled manufacturer packaging or professionally dispensed pharmacy packaging. The packaging should clearly identify the medication name, strength, manufacturer, directions for use, and the Drug Identification Number where applicable.
Be Cautious of Prices That Seem Too Good to Be True
Canadian medications are often significantly less expensive than their U.S. counterparts, but prices that seem dramatically lower than every other Canadian pharmacy deserve additional investigation. A reputable pharmacy focuses on patient safety, regulatory compliance, and professional pharmacy services rather than unrealistic pricing.
Does a DIN Guarantee a Medication Is Genuine?
A Drug Identification Number indicates that Health Canada has approved that medication for sale in Canada.
However, a DIN should be viewed as one important trust indicator rather than the only one.
Patients should always purchase medications from licensed Canadian pharmacies that require valid prescriptions, provide access to licensed pharmacists, and follow Canadian pharmacy regulations.
