Package Tracking (Open Any Carrier's Delivery Status from a Tracking Number)
Package tracking tool: pick a carrier and enter your tracking number to open the official delivery status page of Yamato, Sagawa, Japan Post, DHL, FedEx, UPS and more. Unknown carriers are detected from the number, and check digits catch typos.

What is this package tracking tool?
This package tracking tool lets you enter a carrier and a tracking number (also called a waybill number or inquiry number) and open that carrier's official delivery status page with the number already filled in. In addition to Japanese domestic carriers such as Yamato Transport, Sagawa Express, Japan Post, Seino Transportation and Fukuyama Transporting, it supports international express services like DHL, FedEx and UPS, postal services in the United States, the United Kingdom, Germany, France, South Korea and elsewhere, and courier services in Asia. Even if your shipping notification email does not name the carrier, choosing "Auto-detect" will list candidate carriers based on the number of digits and the pattern of characters.
Before opening a number, the tool also calculates its check digit (a verification digit at the end used to catch input errors). For Yamato Transport and Sagawa Express 12-digit numbers, 13-character international mail numbers (e.g. EJ123456785JP), and numbers from UPS, FedEx, USPS and DHL Express, it applies each carrier's or the international standard's validation method, so most typos can be spotted before you open the page. The delivery status itself is shown on each carrier's official page; this tool does not send your number to our server, nor does it read the delivery status on your behalf.
How to use package tracking
- Choose the carrier From the carrier buttons grouped by region, click the company named on your waybill or shipping notification email. If you do not know the carrier, simply leave "Auto-detect", which is selected from the start.
- Paste the tracking number Numbers with hyphens or spaces, or written in full-width digits, are fine as they are. For multiple packages, put one number per line, up to 20 numbers.
- Press "Find tracking pages" The "Tracking results" section appears below. For each number you will see the carrier, the check-digit result (such as "Check digit matches", "Format matches" or "Check digit mismatch") and the URL of the tracking page. If it does not match, please compare the number with your waybill before opening the page.
- Open the tracking page Press "Open tracking page" and the carrier's official site opens in a new tab with the number filled in. You can also copy just the URL and send it to family members or business partners.
Tips for getting more out of it
- It is normal for auto-detect to show more than one candidate. Yamato Transport and Sagawa Express both use 12-digit numbers and are said to use the same validation method, so the number alone cannot tell them apart. Please choose based on the carrier named in your shipping notification email.
- In a 13-character international mail number (2 letters + 9 digits + 2 letters), the final two letters indicate the country of origin. "JP" means the item was accepted by Japan Post, and "CN" means it was accepted by China Post. Once the item reaches Japan, you can also check its delivery status on Japan Post's tracking page.
- Right after shipping, a carrier may say the tracking number cannot be found even if the number is correct. This is because the number is not registered until the carrier receives the package and scans it for the first time; checking again a few hours later or the next day usually shows it.
- Packages delivered through an online store's own delivery network often cannot be looked up on a carrier's tracking page, and their status may only be visible in the store's order history.
- A "Check digit mismatch" may not appear when 0 and 7, 1 and 8, or 2 and 9 are mistyped for each other. This is a property of methods that use the remainder after dividing by 7; the side note below explains it in detail.
When package tracking comes in handy
Confirming shipments on flea-market apps and online auctions
Before sending a tracking number to a buyer, you can confirm it is correct using its check digit. Paste numbers from several transactions at once and you can jump straight to each tracking page.
Tracking overseas online orders and personal imports
A package coming from abroad passes between the sender country's postal service, an international express company and a Japanese delivery company. Because the tool lists candidates based on the number format, you get a good idea of which company's page to check.
Shipping operations and customer inquiries at work
When a business partner says a package has not arrived, you can paste the number from your shipping records, open the official tracking page and include that URL directly in your reply.
Coordinating deliveries for family members
By copying and sending the tracking page URL, the person receiving the package no longer has to retype the number on the carrier's site.
Package tracking glossary
- Tracking number
- A number assigned to each individual package, used to look up its delivery status on the carrier's tracking page. Depending on the company it may be called a "waybill number", "consignment note number", "inquiry number" or "tracking number", but they all refer to the same thing.
- Check digit
- A verification digit added, for example, to the end of a number. Because it is derived from the other digits by a fixed calculation, a typo makes the calculation fail to match, letting you notice the mistake.
- Modulus 7 (mod 7)
- A method in which the final digit is the remainder when the number without its last digit is divided by 7. It is reportedly used for numbers such as the 12-digit numbers of Yamato Transport and Sagawa Express, and the final digit is always between 0 and 6.
- S10 (UPU standard)
- The format for international mail numbers defined by the Universal Postal Union (UPU). It is 13 characters long: 2 letters + an 8-digit serial number + 1 check digit + a 2-letter country code, and it was introduced in 1996.
- EMS
- An international express mail service operated jointly by postal services around the world. Among S10-format numbers, those starting with E (EA to EZ) are allocated to EMS.
- International express (courier)
- A service, such as DHL, FedEx or UPS, that carries packages across borders from pickup to delivery using a single company's network. These companies use their own numbering systems, separate from postal services.
Frequently asked questions
Side Note — Check digits based on the remainder after dividing by 7 can miss some typos
The 12-digit numbers of Yamato Transport and Sagawa Express are said to have a final digit equal to "the remainder when the other 11 digits are divided by 7". For example, if the first 11 digits are 12345678901, the remainder after dividing by 7 is 3, so the full number becomes 123456789013. Since the remainder can only be 0 to 6, any 12-digit number ending in 7, 8 or 9 is always identified as wrong under this method.
However, this method has some typos it cannot catch. When a single digit is mistyped, the whole number changes by "the difference (1 to 9) × a power of 10". Powers of 10 are not divisible by 7, so only when the difference is 7 — that is, when 0 and 7, 1 and 8, or 2 and 9 are confused — does the remainder stay the same and the error slip through. Swapping two adjacent digits follows the same logic: when the two swapped digits differ by 7 (such as 07 and 70), the error cannot be detected.
The S10 format for international mail multiplies the 8-digit serial number by the distinct weights 8, 6, 4, 2, 3, 5, 9 and 7, adds the results, and determines the check digit from the remainder after dividing by 11. Because 11 is a prime number and the weights are all different and none is divisible by 11, the remainder itself always changes for any single-digit typo or any swap of two adjacent digits. However, because the check digit is only one digit long, there is a rule that replaces "11 − remainder" with 0 when it equals 10 and with 5 when it equals 11, so numbers with a remainder of 0 and numbers with a remainder of 6 both end up with a check digit of 5. Because of this overlap, testing with random numbers shows that about 1.8% of single-digit typos slip through. Even so, compared with about 6.7% for the divide-by-7 method, that is roughly a quarter of the misses.
Neither method can tell you whether a number actually exists. Even if the check digit matches, the number may not yet be registered with the carrier, or it may belong to someone else's package. A check digit is simply a mechanism for "catching obvious typos before you make an inquiry".
