Yep. So you will see on the deed: "PR-{TERRITORY_ABBREVIATION}-{REGION_NUMBER}-{TRACT_NUMBER}-{PLOT_NUMBER}". Tracts are numbered 1 - 10 for each region (1 - 150) and plots are numbered by tract. So your pool should send you something like PR-PNW-001-01-001 - PR-PNW-001-01-100. Of course the region and tract numbers will vary based on where the region is :)
