I haven't queried data from the _Subscribers data view before and faced with that issue. Please correct me if I did something in a wrong way.

At first, I created a temporary data extension with these fields:
SubscriberKey - Text - 254 - nullable
EmailAddress - EmailAddress - 254- nullable
Status - Text - 50 - nullable

A SQL query was created also and targeted to the temporary data extension above. The SQL looks like this:

FROM _Subscribers
WHERE SubscriberKey = '003O000001TzbzvIAB'

And run once. There is nothing returned into the data extension. I tried to remove the line WHERE SubscriberKey = '003O000001TzbzvIAB', it returned 825 results into the data extension.

I also double checked in All subscribers list/Search/Subscriber Key is equal to 003O000001TzbzvIAB and and still found the subscriber.

(Note: I did the query from a Dev Business Unit)

    Are you able to try again with ENT._Subscribers in the query? Commented Jun 16, 2021 at 4:36
  • You are right. ENT._Subscribers is the proper way to query. I have checked the document, it seems Data views only stored records in current 6 months

    The 6 month limitation is only on the views around transient or activity data (Clicks, Bounces, Opens, etc) views like Subscribers contain all relevant subscribers in the account. Commented Jun 16, 2021 at 13:41

I would recommend querying ENT._Subscribers and also go into the All Subscribers section of Email Studio Subscribers & search the subscriber key you care about (003O000001TzbzvIAB). If that subkey exists in All Subs it will also give the corresponding EmailAddress. From there I would recommend running your query to filter on that email address value EG:

FROM ENT._Subscribers
WHERE EmailAddress= '*result from all subs search'

If you still cant find anything there is another way to check contacts information: Go to Contact Builder > All Contacts > Mobile List tab > Create Mobile List > MobileConnect > All Contacts

In the filter: -System Data > EmailAddresses Email Address = '*result from all subs search' OR -System Data > Contact > Contact ID = "003O000001TzbzvIAB"

Hope this helps you,
