Project description Documentation Status Updates

trackr is a lightweight Python lib to access carriers’ tracking information.


pip install trackr

Works with Python 2.7, 3.5 and 3.6.


from trackr import Trackr

package = Trackr.track('ect', 'PN871429404BR')

for t in package.tracking_info:
    print t.location, t.status

Or also using Trackr cli:

$ trackr --carrier=ect --object-id=PN871429404BR

Available carriers

  • ect (brazilian “Correios”)

  • fake (for testing purposes)


Data is retrieved from Correios using its SOAP webservice. For that you’ll need an username and password. Get in touch with your ECT representative to gain acess.

The easiest way to provide the credentials is exporting as env variable:


You can also pass a function keyword args:

package = Trackr.track('ect', 'PN871429404BR', ect_username='**', ect_password='**')


Fake carrier is meant to be used when testing and developing integrations. It will always return as package found with 4 tracking info rows. Example

$ trackr --carrier=fake --object-id=123456789
Package found!

Integrating a new carrier

To add a new carrier, inherit carriers.base.BaseCarrier and fillout _track_single() and/or _track_bulk() methods, it must return one instance or a list of carriers.base.Package instance. See an example below:

from datetime import datetime
from .base import BaseCarrier

class MyOwnCarrier(BaseCarrier):
    id = 'mycarrier'
    name = 'My Carrier'

    def _track_single(self, object_id):

        # ... fetch data from carrier's data source

        package = self.create_package(
            service_name='Express service',

            date=datetime(2017, 1, 1, 10, 00),
            location='Last Location',
            status='In transit to another location'
            description='Get ready!',

            location='Current Location',

        return package

Then update the carrier mapping on trackr/carriers/ (this should be improved with some autodiscover feature). Remember to write tests!


This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.
