Best Practices & Troubleshooting

Best Practices


The best practices specific to YubiEnterprise APIs are in the API Onboarding Playbook.

  • Have at least two Org Owners who can manage members (see Settings).
  • Inform both your YubiEnterprise users and your end-users in advance that they will receive email from Yubico’s YubiEnterprise Delivery. Without this advance notice, they are likely to regard these emails as phishing attempts.
  • Subscription customers:
    • To ensure that you do not let keys in any of your inventories expire unused, create a spreadsheet to plan the allocation of products across users and inventory types. See Example Subscription.
    • When creating a shipment request, select the inventory type before selecting the item(s) to be shipped.

Limits and Constraints

When planning and executing shipment requests, keep in mind the limits and constraints:

  • Each shipping request is limited to 500 items. You can order 500 keys of a single type, or 250 lanyards plus 250 keys of different types, etc.
  • Each CSV file is limited to 1000 shipment requests (bulk shipment)
  • Each CSV file is limited to 10 MB
  • Address validation takes place every 15 minutes. This means that you might have to wait up to 15 minutes to find out if your shipment request has been queued for fulfillment (see Shipping Status Codes).
  • Non-subscription purchases: Shipment requests can be made for up to one year after a PO is submitted.
  • Subscription purchases: Time limits for shipment requests depend on the stock/inventory from which the products are drawn.

The full list of options potentially available is given below. The actual list depends on what you have purchased. Explanations for the terms in the list are given in the table below the list.

With the release of YubiEnterprise Delivery 1.6.0, the distinction between Primary Subscription and Backup Subscription is made explicit, thus facilitating requesting shipment.

Standard Products Subscription Non-subscription
Standard products are
physical keys purchased
outright (on your PO
you will not find
“Standard Products”,
but instead the actual
products/models that
you purchased).

There is a primary
subscription and a backup
subscription for each
tier (product grouping):
Base, Advanced, Premium,
and FIPS. Each of those
tiers has Initial,
Buffer, and Replacement
sub-categories, explained
in the table below,
The non-subscription
tiers are for virtual
keys. Unlike
subscription tiers,
tiers have no


This section addresses issues that can arise with shipping. YubiEnterprise Delivery notifies you of the situation of any given shipment via the codes in the Status column of the Shipments tab. The table below, Shipping Status Codes, lists the error codes and their explanations.

YubiEnterprise Delivery uses an address validation service to reduce the incidence of issues, but it is important to be aware that just because an address exists in Google Maps, it does not mean that the address is deliverable. ‘Deliverable address’ is a United States Postal Service (USPS) classification for designating addresses to which the USPS has historically been able to deliver. YubiEnterprise Delivery’s ability to deliver is based on address information being input in the format acceptable to the USPS. These formats are laid out in detail in the USPS’s Postal Addressing Standards.


When revising an address, the quickest option is to use the format Google Maps presents, because it usually does use the address format preferred by the USPS. In the screenshot below, the address format that was input appears in the upper field, and Google Maps’ format (preferred by USPS) is presented below the photo of the location.


Also, when revising addresses, ZIP / Postal Code is generally a good place to start.

Address Validation Outside the US and Canada

For parts of the world with less standardized address formats, the fact that we can accept an address does not mean that it is deliverable. An address will often be classified as “partially deliverable”, which means that we rely on local couriers who are familiar with the complexities of their urban systems and their delivery routes to deliver to the intended recipient.

Typically packages sent to European addresses and some parts of Asia reach their destination. Packages sent to Southeast Asia and Eastern Europe typically arrive at the right street. In those parts of the world where there are no numbers in the postal addresses, the local courier’s capability is crucial to ensuring that the package does not just end up in the right general area.

Shipping Status Codes

At any of the states between 1 and 9, a shipment request can be edited. From this point on, a shipment request is either processed through to an end state, or set back to state 99.

This table is very wide; scroll horizontally to see all four columns.

(2) Incomplete Address: Secondary line information such as apartment (apt), suite, unit is missing. Therefore it is not possible to guarantee delivery to the correct recipient.

(3) Address is Undeliverable or could not be understood: The address is either not physically deliverable or it could not be resolved to a real location.

(4) Any shipping request with a recipient name and/or address found on the US government’s DPL (Denied Parties/Persons List) cannot be fulfilled.

Shipment Status Messages

As the following table is wide, you may need to scroll horizontally. In the Explanation column, the source of the message is given: YubiEnterprise Delivery system for internal messages, US Validation for the US Postal Service, and finally, International Validation. Messages originating from the last two are simply passed on to you by YubiEnterprise Delivery.
