A1 POST is a courier and postal-service brand operated by A1 Trade EOOD in Bulgaria. The company provides shipment services through its Bulgarian postal and courier network, serving individuals and businesses that need to send documents and packages while managing their deliveries through an online platform.
For domestic shipping in Bulgaria, A1 POST's official terms cover courier shipments weighing up to 31.5 kg. Its service framework also includes additional options such as declared value, return receipt, return documents and storage when a shipment remains at an A1 POST office after the applicable notification period.
A1 POST also supports international courier shipping from its Bulgarian operation for packages weighing up to 31.5 kg. Its pricing system distinguishes between options without tracking, with Tracking, and with Tracking plus signature for applicable shipments, allowing customers to choose a level of shipment visibility suited to the service they purchase.
The company promotes an integrated delivery-management platform and integration with major marketplaces and e-commerce platforms. For recipients, package tracking is the most direct way to follow a shipment because A1 POST records events as the package is accepted, processed, moved through facilities and, where applicable, transferred to a delivery partner.
How A1 POST shipment tracking works
A1 POST's official tracking page asks for a tracking number, while the Bulgarian version describes the reference as the number on the waybill. Entering this reference allows the system to retrieve the shipment events associated with the package.
To Track an A1 POST package with 4Tracking, enter the tracking or waybill number in the tracking field. 4Tracking can automatically identify the supported carrier; select A1 POST if necessary and press the Track button. You will then be redirected to the results page, where the available package tracking events are shown in chronological order.
A1 POST's own Tracking pages can display events such as shipment information uploaded, package processed, loaded for transport, departed from the A1 POST terminal, pickup scan, arrival at a facility and delivery. Some shipments are handed to partner carriers, and the official tracking page may provide an additional option to continue Tracking with that delivery partner.
A1 POST tracking number formats
A1 POST does not publish one universal fixed-length format for every tracking number or waybill number. Its official Tracking system shows that references can vary, particularly when shipments are connected with partner-carrier networks.
Official A1 POST tracking records demonstrate the use of long numeric references as well as postal-style identifiers containing both letters and numbers. Because these formats can differ, it would be inaccurate to state that every A1 POST package must have the same number of characters or follow one prefix pattern.
Use the complete tracking number exactly as provided by A1 POST, the sender or the shipping documentation. If the number is not recognized, check for missing characters, unnecessary spaces or confusion between the merchant's order number and the actual carrier waybill number.
A1 POST delivery times and supported examples
A1 POST does not publish one general delivery-time range that applies to every package in Bulgaria. Its official terms state that services can have their own type, price and specific conditions, so the relevant delivery commitment depends on the service purchased and the conditions recorded for the shipment.
One specific timing rule is published in A1 POST's terms: when a contracted delivery period is 1 working day, the deadline is considered to be the end of the following working day. This is an example of how a one-working-day commitment is calculated and should not be interpreted as a promise that every A1 POST shipment is delivered within one working day.
For other shipments, customers should rely on the agreed service conditions and current Tracking events rather than assuming a fixed number of days. A1 POST's terms specifically recognize claims when agreed delivery deadlines are not met for shipments transported within Bulgaria.
When a package is waiting at an A1 POST office, the recipient can be notified by SMS, telephone or email. Under the company's courier terms, storage charges can begin after two working days from notification that the shipment is available at the delivery office, or after an undelivered shipment is returned to an A1 POST office for reasons outside the carrier's responsibility.
How to contact A1 POST about shipment issues
If Tracking has stopped updating, the package is overdue or another delivery problem occurs, keep the tracking or waybill number ready when contacting A1 POST. The company's official website lists the customer contact number as +359 888 00 78 00.
A1 POST lists its working hours as Monday to Friday, 08:30 to 17:30. Its published address is 281 Vladislav Varnenchik Boulevard, Varna, Bulgaria. The company's official terms also provide info@a1post.bg as an email contact.
For more serious shipment problems, A1 POST's terms allow both the sender and recipient to submit a claim for delayed, lost, damaged, stolen or destroyed shipments. A claim can generally be submitted within 6 months from the date the shipment was accepted. For a domestic shipment claim in Bulgaria, A1 POST states that it has up to 1 month from submission to investigate and provide a written response, subject to extensions when information is incomplete.
If damage is noticed when receiving the package, the company's terms instruct the recipient to inspect the contents in the presence of an A1 POST employee so that a report describing the damage can be prepared. Keeping the shipment documents and tracking reference will help support any subsequent claim.
Frequently asked questions about A1 POST package tracking issues
What number should I use to Track an A1 POST package?
Use the A1 POST tracking number or waybill number supplied for the shipment. The Bulgarian official tracking page specifically asks for the number on the waybill.
What format does an A1 POST tracking number use?
A1 POST does not publish one fixed format that covers every shipment. Its official Tracking system handles different reference styles, including numeric and alphanumeric identifiers, so enter the complete number exactly as supplied.
Why is my A1 POST tracking number not working?
Check that you entered the carrier tracking or waybill number rather than an online-store order number. Verify every character and remove accidental spaces. If shipment information has only recently been created, Tracking events may also not yet be available.
Why does A1 POST Tracking show a partner carrier?
Some packages continue through a partner delivery network. In these cases, A1 POST's official tracking page can display a link to Track the shipment with the partner carrier as well as the events recorded within the A1 POST system.
How long does A1 POST delivery take in Bulgaria?
A1 POST does not publish one universal delivery period for every domestic shipment. The timing depends on the contracted service. Its terms state that when a service has a one-working-day delivery commitment, that period ends at the end of the following working day.
What should I do if my A1 POST package is delayed?
Check the latest package tracking events and compare them with the agreed delivery conditions for your shipment. If the contracted deadline has passed without delivery, contact A1 POST with the waybill number so the shipment can be investigated.
Can I make a claim for a lost or damaged A1 POST package?
Yes. A1 POST's official terms provide a claims process for delayed, lost, damaged, stolen or destroyed shipments. The sender or recipient can generally submit a claim within six months from the shipment's acceptance date.
What should I do if my A1 POST package arrives damaged?
Inspect the contents when receiving the shipment and, when possible, do so in the presence of an A1 POST employee. The company's terms provide for a damage report to be prepared when a problem is discovered at delivery, which can support a subsequent claim.
How do I contact A1 POST about Tracking problems?
You can contact A1 POST at +359 888 00 78 00 during its published Monday-to-Friday working hours of 08:30 to 17:30. The official terms also list info@a1post.bg as an email address.
