Here are some examples of 1.5 circuit IDs that Verizon New England uses:

95/HCG(S)(L)/xxxxxx Massachusetts (Eastern & Central).
91/HCG(S)(L)/xxxxxx Massachusetts (Western).
87/HCG(S)(L)/xxxxxx Vermont (Entire State).
85/HCG(S)(L)/xxxxxx Rhode Island (Entire State).
83/HCG(S)(L)/xxxxxx New Hampshire (Entire State).
81/HCG(S)(L)/xxxxxx Maine (Entire State).

SBC/SNET uses 2 types of ID for their 1.5's in Conneticut:

FA/HCG(S)(L)/xxxxxx
HCG(S)(L)/xxxxxx
 
All ckt IDs used by the ILECs have a specific format. This format has been around since the Bell System days. It also is a BellCore and OBF standard for all companies that want to play the telco game in access service or special access service. The ID consists of several pieces. The first two characters are for the PCO, Maintenance Center, or Wire Center. The next four characters indicate the type of special service and type of use, ie inter/intra lata and generic or type of provider, ie paging, CMRS, IC, or gov. The last portion can be a six digit serial or nine digit serial number. It is usually followed by two to four letters, ie PT or GT or GTEW. The letters identify the operating company where that portion of the circuit resides or originates. Some of the suffix parts are optional.

99 HCFV 916000-001 PT

But carriers like MCI, Sprint, & others use their own formats on the customer side. AT&T uses the standard format minus the PCO prefix. Now if the ckt is from someone other than an ILEC, each entity may ID the ckt, then you have multiple IDs. For example, I have an MCI ckt, NP32387-0001, point-to-point T1. At each end there is a local loop. Each local loop has its own ID, 42HCGS005008-862PT and 90HCGS005009-123PT. Since they are pieces of the total ckt the main carrier or access provider uses one ID to reference the ckt and all its pieces for billing, provisioning and maintenance. The end parts are also called end links and the MCI part is called a mid link. So when an installer puts in a ckt of whatever flavor and it comes from AT&T, MCI, PAETEC or whomever the ID tag should have two IDs on it.

Now backing up a little bit, as far as carrier specific information on ckt IDs for awhile back in the late 1980s and 1990s some of the ILECs used specific number ranges in the six digit serials for INTEREXCHANGE CARRIER ckts. This came from their ICID code that was assigned when they became access carriers. For example MCI had 005 as their ICID in Pacific Bell/Nevada Bell territory. If I remember correctly Sprint is 030. In the late 1990s some of this changed to non-specific series in some areas. So unless you are familiar with the ID formats of the service providers you may or may not be able to tell whom the provider is.

As mentioned above 'HCFS orDHZA' does NOT indicate any specific carrier since they are only part of the ckt ID! The part that describes the type of service.

Hope this helps!
