While wandering through a store in Boston's Downtown Crossing, I happened to come across a sign at the entrance to a major retailer that said, "Only Registered Services Animals Permitted." This raises a question that many retailers and commercial offices have: what kinds of restrictions can they impose on service animals? A policy that demands "registration" of service animals may not be a good idea.

The Massachusetts Attorney General's Office provides a useful webpage answering many of the important compliance questions that businesses have.

A couple notable statements that I would draw attention to: "Currently, there is no state or national certification available for service animals so businesses are not permitted to inquire if the animal is licensed or certified or whether the animal has identification papers." 

Also: "To differentiate between pets and service animals, businesses can ask the person with a disability if the animal is a service animal required because of a disability. They can also ask what tasks the animal has been trained to perform. Once an individual answers these questions the business may not question them further or separate the animal from the individual except as noted above. Businesses may not inquire about the individual’s disability."

The underlying body of law rests on the principle that persons with disabilities should have access to businesses and public spaces. In turn, businesses and offices should probably use policies that favor access over restrictions.
In July of 2015, a new low-cost legal services agency dedicated to assisting transgender individuals in New England went live: Transformative Justice Legal Service (TJLS). This law practice, along with  is proud to be a chief supporter of TJLS. Updates and a link to TJLS new survey of the legal needs for transgender individuals can be found on its Facebook page

More broadly, the national and regional picture for transgender equality and employment protections is changing. The EEOC recently solidified its long-developing position on anti-discrimination protections by formally announcing that it considers discrimination on the basis of sexual orientation and gender identity to be forms of sex discrimination. This should come as a welcome clarification to all workers and employers.
