DIN vs. MDEL: Which Number Proves What

A DIN or an NPN is issued to a product; an MDEL is held by an establishment. The code on the box confirms that a specific formulation is authorised for sale in Canada, while the establishment licence confirms who may legally import or distribute devices, and under what scope. Buyers mix the two because both arrive as a short string on the same invoice.

What does a DIN or NPN prove about a product?

A DIN — Drug Identification Number — is assigned to a drug product under the Food and Drug Regulations (C.R.C., c. 870). It attaches to one formulation, one manufacturer and one set of claims, and it appears on the label in a fixed format that you can confirm in Health Canada's Drug Product Database.

An NPN does the same job for the natural health product category, issued under the Natural Health Products Regulations (SOR/2003-196) and listed in the LNHPD. Change the manufacturer or the formulation and the old number no longer applies.

Neither number describes the seller. A DIN says nothing about whether the establishment that shipped your case keeps distribution records or holds a recall procedure.

What does an MDEL cover that a product number does not?

A Medical Device Establishment Licence is required for any establishment in Canada that imports or distributes medical devices for sale, under the Medical Devices Regulations (SOR/98-282). It covers all device classes, including Class I devices that never receive a licence of their own.

One MDEL covers premises and activities rather than products. It names what the establishment may do — import, distribute, wholesale — and the holder must keep distribution records, a complaint process, recall procedures and incident reporting, across every device line the establishment handles.

Read the table down the second column: two rows belong to products, two belong to establishments.

Why do Canadian buyers confuse the two?

Both codes are short, both get quoted on invoices, and both are called "the number" in conversation. Someone hunting for a supplier's licence number and handed a product number instead has no easy way to tell them apart.

The same supplier often holds both. A distributor may hold an MDEL and also sell drug products whose labels carry a DIN, so one invoice can show both codes side by side.

Scope is the other trap. An MDEL for distribution does not cover importing unless import is named on it, and no MDEL can vouch for a product with no DIN, NPN or device licence.

Which documents should you collect before ordering?

Start with the establishment, then move to the products.

• The MDEL number, its expiry date and the activities the licence names
• A device licence number for each Class II, III or IV device on the quote
• The DIN or NPN as printed on the label, matched to your formulation and pack size
• A written statement of the supplier's distribution record, complaint and recall procedures
• Test documentation where performance matters, such as a certificate of analysis for a glove lot

Keep the file with the purchase order, not in a supplier folder. If a recall notice lands two years later, the distribution records tied to that MDEL tell you whether your lot is affected.

How do you verify a supplier claim?

Three checks cover most of it. Look up the establishment licence number and confirm that the status is active and the activities match what you are buying. Look up the product number and confirm that the label matches the entry. Ask for the records commitment in writing, since record keeping is what an MDEL obliges the holder to do.

The certifications page collects the documents we hold, and the compliance log centre shows how those records look in everyday clinic use. CliniEco Medical operates under Health Canada MDEL #35334.

A worked example of both routes: a clinic-pack hand sanitizer carries an NPN on the bottle, while 4 mil nitrile examination gloves are Class I devices whose Canadian importer or distributor needs an MDEL, with no device licence number on the box.

Sites evaluating monitoring alongside the same compliance file can test the readout with a rapid reader seed trial before choosing a system.

Frequently Asked Questions

Is an MDEL the same as a product licence?
No. An MDEL belongs to an establishment and covers activities such as importing or distributing devices. A product licence belongs to a product, and for drug or natural health products its equivalent is a DIN or an NPN.

Where do I check a DIN or an NPN?
Search the Drug Product Database for a DIN and the LNHPD for an NPN. Match your label against the entry: manufacturer, formulation and pack size all have to line up.

Where can I check an MDEL number?
Establishment licences are listed in the Medical Devices Active Licence Listing, known as MDALL. Check the status, the expiry date and the activities named, because distribution and import are separate activities.

Do gloves and hand sanitizer carry the same number?
No. Examination gloves are Class I devices, so their Canadian importer or distributor holds an MDEL and no device licence number appears on the box. A hand sanitizer labelled with an NPN, such as NPN 80122015, follows the natural health product route.

What should I ask a supplier for before the first order?
The MDEL number with its expiry and activity list, a device licence number for any Class II or higher device, the DIN or NPN matched to the label, and a written statement covering records, complaints and recalls.

CliniEco Medical is a licensed medical device establishment (MDEL #35334).
